This application is a continuation of U.S. application Ser. No. 16/180,663, filed Nov. 5, 2018, which is a continuation-in-part of U.S. application Ser. No. 15/608,617, filed May 30, 2017, now U.S. Pat. No. 10,175,031, issued Jan. 8, 2019, which claims the benefit of U.S. Provisional Application No. 62/342,485, filed May 27, 2016, the entirety of the disclosures of which are incorporated by reference herein.

FIELD OF THE DISCLOSURE

Embodiments of the disclosure are directed to an aiming device. Specifically, embodiments of the disclosure are directed to a system for reticle configuration in an aiming device, such as a rifle scope, thermal scope, smart scope, digital scope, or the like.

BACKGROUND

Many firearms, such as rifles, are equipped with an optical aiming device, such as a rifle scope, that provides the user with an image of an aligned aiming point or pattern (commonly known as a reticle) superimposed at the same focus as the target.

When shooting at long distances, shooters must adjust their aim to take into account the downward acceleration on the projectile imparted by gravity, which is often referred to as “bullet drop.” In some instances, this is done by adjusting the angular position of the optics of the rifle scope relative to the rifle barrel using an elevation turret. Similarly, a shooter may also adjust for left-to-right movement due to wind using a windage turret.

Additionally, the optical aiming device can be outfitted with a ballistic drop compensation (“BDC”) reticle that includes a reticle pattern for assisting a shooter to predict bullet drop at various ranges. The reticle can include a pattern with several different holdover marks stacked vertically beneath a central dot or crosshair which represents a zero mark. As such, when a firearm is zeroed to a certain range at the central crosshair, the stacked holdover marks will correspond to the bullet's impact at longer ranges. Accordingly, a shooter can choose an aiming point corresponding to one of the holdover marks or a point in between.

Humidity, elevation, temperature, grain size, bullet velocity and other various factors affect the flight of a bullet and the amount of bullet drop. As such, fixed-position BDC holdover marks do not consistently represent ranges. Furthermore, depending upon the above factors, the ranges represented can vary significantly, requiring calibration and experience for a shooter to accurately predict bullet drop and to use the BDC reticle.

Previous attempts to provide a BDC reticle are shown and described in U.S. Pat. Nos. 7,703,679; 6,269,581; and in U.S. Pub. No. 2015/0247702; each incorporated by reference herein in their entirety.

SUMMARY

One or more embodiments of the disclosure are directed to an optical aiming device including a configurable ballistic drop compensation (BDC) reticle. In various embodiments, the reticle includes a BDC pattern, including one or more BDC holdover marks, that is configurable based on a plurality of weapon and ammunition pairings. For example, one or more embodiments of the disclosure provide for customizable placement of BDC holdover marks in a reticle pattern, where the placement corresponds to user-selected ranges or impact points for a particular weapon and ammunition pairing. In various embodiments, the positions of the BDC holdover marks in the reticle pattern are based on a determined ballistic trajectory path for the particular weapon and ammunition pairing.

Accordingly, various embodiments improve shooter accuracy at range, as the BDC pattern is specifically configured to indicate user designated ranges for the particular weapon and ammunition pair. This provides an improvement compared to BDC reticles with a static BDC pattern, as the static pattern may include holdover marks that are not positioned based on the gun and cartridge combination for which the optical aiming device is being used. Instead, if a user desires that the holdover marks in the static BDC pattern correspond to one or more specific ranges, the reticle may need to be designed based on that particular weapon and ammunition pair.

Additionally, one or more embodiments improve scope utility by allowing for various configurable BDC patterns for use with a plurality of different weapon and ammunition pairings. For example, for static BDC patterns, if the gun and/or ammunition changes, the holdover marks, which may be lines, of the pattern will have an entirely different meaning with regard to ranges. As such, the shooter would need to determine the new ranges indicated by the holdover marks, or utilize a reticle with a different BDC pattern. Similarly, if a user changes their preferences as to what ranges should be indicated by the BDC pattern, the reticle again would need to be replaced with one utilizing a different pattern.

Accordingly, one or more embodiments of the disclosure are directed to a system for configuring an optical aiming device for ballistic drop compensation (BDC). In one or more embodiments the optical aiming device including a housing with a reticle pane defining a reticle display field viewable by a user and indicating a zero point.

DETAILED DESCRIPTION

FIG. 1A depicts an ocular aiming device 100 according to one or more embodiments. In various embodiments, the ocular aiming device 100 includes a housing 104 formed from an exterior tube 108. In certain embodiments, the housing 104 extends between a forward portion 112 that defines a bell portion 116 and a rearward portion 120 that defines an eyepiece portion 124. In one or more embodiments, the housing 104 is generally tubular shaped and defines an optical passageway for light to pass therethrough, along a central axis 128. In certain embodiments, the device 100 includes an ocular lens 132 positioned in the eyepiece portion 124 and an objective lens 136 positioned in the bell portion 116. In one or more embodiments, the device 100 includes an erector tube 140 mounted internally in the device 100 and co-axial with the housing 104.

In various embodiments, the erector tube 140 includes a reticle pane 144 and one or more axially spaced erector lenses 148, 149, 150, mounted within for magnification and creation of a reticle display field in the optical pathway. As used herein, reticle display field refers to a reticle and various other indicators or marks that are visible to a user when viewing through the optical aiming device. In one or more embodiments the erector tube 140 is connected to the exterior tube 108 via a pivoting frame for adjustments to the angle of the erector tube 140 relative to the housing 104 for elevation and windage adjustments. Accordingly, in certain embodiments the device 100 additionally includes an elevation adjust knob or turret 152 and a windage adjust knob or turret (not shown) for pivoting the erector tube 140 for such adjustments.

The reticle pane 144 is a pane or lens of transparent material that is viewable in the device 100 by a shooter through the ocular lens 132. In various embodiments, the reticle pane 144 includes a reticle or pattern for directing the aim of a shooter. When viewed through the device 100 a shooter will observe a reticle display field, defined at least in part by the reticle pane 144, which includes the reticle or pattern. For example, in various embodiments the reticle pane 144 includes a physical reticle of two etched lines, wires, or the like, that form a crosshair in the reticle display field and form a portion of the reticle. Described further herein, in some embodiments, reticle pane 144 is blank and has a digitally projected reticle or pattern that is reflected onto the reticle pane 144 to form a crosshair, or other suitable aiming mark in the reticle display field.

Depicted in FIG. 1A, the reticle pane 144 is positioned in the first focal plane, at a forward portion 156 of the erector tube 140. However, in certain embodiments, the erector lens 150 could instead be configured as a reticle pane, such that the reticle pane is positioned in the second focal plane at the rearward portion 160 of the erector tube 140. In some embodiments, the erector tube 140 can include multiple reticle panes positioned at both the forward portion 156 and at the rearward portion 160 of the erector tube 140. As such, described further below, in various embodiments the

In various embodiments, the device 100 includes a display device 164 for projecting a digital image onto the reticle pane 144. In one or more embodiments, display device 164 includes a display 166, lens 168 and a prism 172 positioned internally within the housing 104. As used herein, prism 172 refers to a glass or other transparent object in prism form, in some embodiments, prism includes a transparent object including two or more refracting surfaces at an acute angle with each other. In some embodiments, prism 172 is a beam splitter. For example, in certain embodiments, prism 172 is a dielectric mirror, beam splitter cube, coated mirror, reflective surface or other suitable type of beam splitter.

In one or more embodiments, the display 166 is any suitable type of display device including, but not limited to, an organic light emitting display (OLED), a standard light emitting diode (LED) display, a liquid crystal display (LCD), and a digital micro-mirror display. In certain embodiments, display device 164 can be any combination of devices for projecting an image onto the reticle pane 144.

Depicted in FIG. 1A, display device 164 is positioned within the housing 104 and in the optical pathway such that at least some portion of the incoming light from the objective lens 136 passes through the prism 172. In some embodiments, the prism 172 display device 164 is fully transparent such that the display device 164 does not significantly obscure or block the light passing through the prism 172. Further, while FIG. 1A depicts the display device 164 as being positioned in the optical pathway, in some embodiments, display device 164 is offset from the optical pathway such incoming light does not interact with the prism 172 or other display device 164 elements.

The size of the prism 172 and display device 164, relative to the housing 104 and the optical pathway within the device 100, as depicted in FIG. 1A are for clarity rather than an actual depiction of the relative sizes of the components. As such, in various embodiments, the size of the prism 172 and other components of the display device 164 could be larger or smaller relative to the size of the housing, the optical pathway, and other elements of the device 100.

In operation, in one or more embodiments, the display 166 emits an output image for projection onto the reticle pane 144 to define the reticle display field. The lens 168 focuses the output image toward the prism 172, which is reflected and projected upon the reticle pane 144, modifying the reticle display field to include the output image. As such, when a user views the reticle pane 144, the output image appears overlaid onto the original reticle pattern. Accordingly, and described further in FIG. 3, the reticle pattern is customizable based on the emitted image from the display 164.

Described further with reference to FIG. 2, in various embodiments, the display device 164 is communicatively coupled with various electronic circuitry for control of the display device 164. In certain embodiments, the housing 104 will provide the necessary space for mounting the electronic circuitry, as well a portable power supply for generating and projecting images onto the reticle pane 144. However, in certain embodiments, some or all of the electronic circuitry is mounted externally to the housing 104.

FIG. 1A depicts the display device 164 positioned in the housing 104 forward of the reticle pane 144, positioned between the objective lens 136 and the erector tube 140. As a result, in various embodiments, the image or reticle pattern projected onto the reticle pane 144 by the display 166 and prism 172 is magnified by the erector lenses 148, 149, 150. In addition, FIG. 1A depicts a single display device 164 positioned in the housing 104. However, in various embodiments, the device 100 could include two or more display devices and/or a display device positioned rearwardly in the housing, between the erector tube 140 and the ocular lens 132.

For example, referring to FIG. 1B, an ocular aiming device 102 is depicted, according to one or more embodiments. In various embodiments, the ocular aiming device 102 is substantially similar to ocular aiming device 100 in FIG. 1A, and includes a housing 104, ocular lens 132 positioned in the eyepiece portion 124, an objective lens 136 positioned in the bell portion 116, and an erector tube 140 including reticle pane 144 and erector lenses 148, 149, 150. In various embodiments, ocular aiming device 102 includes a first display device 164 and a second display device 176. Second display device 176 is substantially the same as first display device 164, including a display 166, lens 168 and prism 172 configured to project an image from the display 166 onto the reticle pane 144. As a result, in certain embodiments, the reticle pane 144 can include two or more overlapping images each projected by different display devices, allowing for more complex reticle patterns or images. In various embodiments, the second display device 176 is positioned rearwardly in the housing 104, between the erector tube 140 and the ocular lens 132 and is configured to project an image onto the second reticle pane, onto the erector lens 150. As a result, in various embodiments, the image projected onto the erector lens 150 by the display 166 is left un-magnified. This configuration can be particularly helpful when the display device 176 is projecting text or other information or where certain portions of the projected image are preferred not to be magnified.

While FIGS. 1A-1B depicts the ocular aiming device 100, 102 as a rifle scope or telescopic sight, in certain embodiments, the ocular aiming device 100, 102 could be any type of suitable sighting device. For example, the optical aiming device 100, 102 could be a reflex sight, holographic sight, digital scope, or other type of sighting device.

FIG. 2 depicts a system architecture for electronic circuitry in an optical aiming device 200, according to one or more embodiments of the disclosure. In various embodiments, optical aiming device 200 is the same or substantially similar as optical aiming device 100 depicted in FIG. 1. The electronic circuitry of the optical aiming device 200 includes a processor 204, a memory 208, network adaptor 212, input/output (I/O) interface 216, display 164, and a bus 220 that communicatively couples various system components.

Processor 204 is a collection of one or more logical cores or units for receiving and executing instructions or programs. For example, in one or more embodiments, processor 204 is configured to receive and execute various routines, programs, objects, components, logic, data structures, and so on to perform particular tasks or implement particular abstract data types.

Memory 208, is a collection of various computer-readable media in the system architecture. In various embodiments, memory 208 can include, but is not limited to volatile media, non-volatile media, removable media, and non-removable media. For example, in one or more embodiments, memory 208 can include random access memory (RAM), cache memory, read only memory (ROM), flash memory, solid state memory, or other suitable type of memory. In one or more embodiments, memory 208 includes any media that is accessible to the electronic circuitry in the optical aiming device 200. For example, in some embodiments, memory 208 includes computer readable media located locally in the optical aiming device 200 and/or media located remotely to the optical aiming device 200 and accessible via a network.

In certain embodiments, further described with reference to FIG. 5, memory 208 includes at least one program product having a group of one or more logical instructions that are executable by the processor 204 to carry out the functions of the various embodiments of the disclosure.

Bus 220 represents one or more of any of suitable type of bus structures for communicatively connecting the electronic circuitry of the device 200. In various embodiments the bus 220 includes a memory bus or memory controller, a peripheral bus, and a processor or local bus using any of a variety of bus architectures.

In various embodiments, the I/O interface 216 facilities communication between the various components of the electronic circuitry. For example, in one or more embodiments, I/O interface 216 is communicatively coupled with the display 164, processor 204 and memory 208 for emitting an output image via the display 164. For example, in certain embodiments, the processor 204 generates an output that corresponds to a particular BDC pattern. The processor 204 can transmit this output the I/O interface 216 which can then translate the processor output into instructions which are compatible with the display 164 and which result in the display 164 emitting an image corresponding to the BDC pattern.

In certain embodiments the I/O interface 216 facilitates communication with input and output devices for interacting with a user. For example, I/O interface 216 can communicate with one or more devices such, as a user-input device 224 and/or an external display 228, which enable a user to interact directly with the device 200. User-input device 224 may comprise a keyboard, one or more push-buttons, a touch screen, or other devices that allows a user to input information. External display 228 may comprise any of a variety of visual displays, such as a viewable screen, a set of viewable symbols or numbers, and so on.

In one or more embodiments, network adaptor 212 enables communication with one or more external computing devices via one or more network protocols. For example, in various embodiments, optical aiming device 200 can communicate using one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter 212. In certain embodiments, network adaptor 212 communicates wirelessly, transmitting and receiving data over air. For example, in certain embodiments network adapter 212 can communicate using Wi-Fi, BLUETOOTH®, or other suitable form of wireless communication. In some embodiments network adapter 212 can communicate to an external computing device via a wired connection.

FIG. 2 is only one example of a suitable system and is not intended to suggest any limitation as to the scope of use or functionality of the embodiments described herein. Regardless, the depicted system architecture is capable of being implemented and/or performing the functionality as set forth herein.

Referring to FIGS. 3A-3E, a variety of reticle display fields 300, 304, 308, 309, 310 are depicted, according to one or more embodiments of the disclosure. In various embodiments, each of the reticle display fields 300, 304, 308, 309, 310, include a BDC pattern reticle 300 a, 300 b, 300 c having a crosshairs with intersecting horizontal line 316 and vertical line 320. The horizontal line 316 and vertical line 320 intersect to form a central zero mark 312 which denotes a zero point. The zero point is determined when sighting a firearm at a known distance by adjusting the angular position of an optical aiming device relative to the barrel of a firearm until the impact point of a fired projectile matches the zero point on the reticle display field 300, 304, 308 309, 310. Consequently, the zero point indicates a first known distance or range.

To target ranges greater than the first known distance, a shooter may adjust the elevation of the scope, thus changing the zero point, or simply shift aim vertically to adjust for bullet drop at ranges beyond the first known distance. For example, in certain embodiments, the reticle display fields 300, 304, 308, 309, 310 each include a plurality of BDC holdover marks 324. The BDC holdover marks 324 provide a visual indication of a vertical shift required to fire a projectile at a range beyond the zero point. In some embodiments, the reticle display fields 300, 304, 308, 309, 310 also include a plurality of windage adjustment marks 328. Windage adjustment marks provide visual indications of lateral shift for compensating for deflecting crosswinds.

In various embodiments, some or all of the lines in the reticle display field 300, 304, 308, 309, 310 are generated or projected upon a reticle pane by a display. For example, the one or more of the horizontal line 316, vertical line 320, BDC holdover marks 324, and windage adjustment marks 328 could be projected upon a reticle pane via a display, such as display device 164 described with reference to FIGS. 1 and 2.

Accordingly, in one or more embodiments, the reticle display field 300, 304, 308, 309, 310 is entirely customizable. For example, instead of a crosshairs, zero mark 312 could be displayed as a duplex reticle, target dot, MILDOT, circle dot, or other suitable type of reticle. Similarly, in various embodiments, the BDC holdover marks 324 and/or windage adjustment marks 328 can be moved, removed, added, or have other modifications based on the output image of a display.

Accordingly, FIGS. 3A-3E depict configurable reticle display field 300, 304, 308, 309, 310 that include projected BDC holdover marks 324 and/or windage adjustment marks 328, according to one or more embodiments of the disclosure.

FIG. 3A depicts BDC holdover marks 324 including a first holdover mark 332 and a second holdover mark 336. The first holdover mark 332 and second holdover mark 336 can be set to indicate various ranges that are greater than the range of the zero point in order to compensate for bullet drop. In various embodiments, the first and second holdover marks 332, 336 include holdover points 314 a 1, 314 b 1. The holdover points 314 a 1, 314 b 1 are points of intersection between vertical line 320 and holdover marks 332, 336. As such, holdover points 314 a 1, 314 b 1 denote aiming points for firing at the ranges indicated by the holdover marks 332, 336.

In various embodiments, these ranges are user-selected. For purpose of example, the first holdover mark 332 could be user-selected to indicate a range of two-hundred yards while the second holdover mark 336 could be user-selected to indicate a range of four-hundred yards. In one or more embodiments, the position of the first and second holdover marks 332, 336 is based on a ballistic trajectory determined from ballistics data for a particular weapon and ammunition combination. For example, in one or more embodiments a first type of ammunition and a first type of weapon will generate BDC holdover marks 324 in FIG. 3A.

FIG. 3B depicts a reticle display field 304 including BDC holdover marks 340, 344 positioned based on a second ballistic trajectory. The second ballistic trajectory is different from the first ballistic trajectory as a result in a change in ballistics data. For example, the ballistics data could change as a result of a change in the type of ammunition, weapon, or due to other factors such as altitude, humidity, temperature, and air density. Holdover marks 340, 344 indicate the same ranges as holdover marks 332, 336 depicted in FIG. 3A (two-hundred yards and four-hundred yards). However, due to the change in the ballistic trajectory, the position of holdover marks 340, 344 has been altered to accommodate or new bullet drop compensation. Similarly as with FIG. 3A, holdover marks 340, 344 include holdover points 314 a 2, 314 b 2, denoting the points of aim for firing a projectile at the ranges indicated by the holdover marks 340, 344.

In one or more embodiments, the holdover marks of various BDC patterns, for example, the marks of FIG. 3A and the marks of FIG. 3B are displayed concurrently. As such, in certain embodiments, the reticle display field can include one or more BDC patterns simultaneously to facilitate quick changes of ammunition without the need to reconfigure the reticle, or for other reasons. In various embodiments different BDC patterns can be differentiated in the reticle display field by using a separate display color for each of the BDC patterns.

In FIG. 3C the BDC holdover marks 340, 344 are substantially the same as in FIG. 3B, and again indicate ranges of two-hundred and four-hundred yards. BDC holdover marks 348, 352 are added to the pattern 308, indicating additional ranges along the second ballistic trajectory. For example, BDC holdover marks 348, 352 could indicate yardage of three-hundred yards, and six-hundred yards, respectively. Similarly with regard to FIG. 3B, holdover marks 348, 352, include holdover points 314 c 3, 314 d 3, denoting the points of aim for firing a projectile at the range indicated by the holdover marks 348, 352.

In addition windage adjustment marks 356, 360 have been added to the reticle pattern 308. In various embodiments, additional BDC holdover marks 348, 352 and additional windage adjustment marks 356, 360 are added to the reticle display field 308 in response to receiving input from a user requesting additional range indications. Furthermore, in some embodiments, the holdover marks 340, 344 can be modified to indicate various other ranges at any time in response to user input. For example, holdover marks 340, 344 could be modified to indicate one-hundred and twenty five yards, and one hundred and fifty yards, respectively, or any other suitable range along the second ballistic trajectory.

FIGS. 3D-3E depict BDC holdover marks 324 including a first holdover mark 332 and a second holdover mark 336.

However, it is intended that the magnification settings at which the secondary reticle 920 is configured to appear or disappear can entirely vary based on the preferences of a user.

As such, in various embodiments an optical device can be configured for automatic alteration of the reticle display field 900 a, 900 b, 900 c, 900 d. In such embodiments a device can be configured to modify or otherwise alter a reticle image that is presented to a user based on an expected engagement range. As a result, in various embodiments the device can be configured to present a reticle image most suitable for the expected engagement range/magnification settings of the device.

Referring to FIG. 10, a flowchart diagram of a method 1000 of automatic configuration of the reticle display field in an aiming device is depicted, according to one or more embodiments. In various embodiments, the method 1000 is implemented with an optical aiming device such as optical aiming device 800 depicted in FIG. 8. However, various embodiments apply to other types of aiming devices, such as a camera-based aiming device, described further below with reference to FIG. 13.

In certain embodiments the expected engagement range for the magnification setting can be determined via pre-determined a lookup-table that includes associations between various magnification settings and engagement ranges. In some embodiments, the lookup-table can simply include associations between various magnification settings and reticle designs/secondary reticles. In such embodiments, the connection between engagement range and magnification settings can be determined prior to use, with the resulting associations between various reticles and device magnification settings programmed into the lookup-table stored in memory. In some embodiments the expected engagement range could be determined via an algorithm in real-time.

In one or more embodiments, at decision block 1012, the method 1000 includes determining whether the secondary reticle is configured for target engagement within the expected engagement range. In various embodiments, by determining whether the secondary reticle is configured for use within the expected engagement range, the aiming device can then modify or otherwise alter a reticle image that is presented to a user based on the determined expected engagement range. As a result, in various embodiments the aiming device can be configured to present a reticle image most suitable for the expected engagement range/magnification settings of the device.

For example, in certain embodiments the expected engagement range for the secondary reticle can be determined via pre-determined a lookup-table that includes associations between various secondary reticle designs and engagement ranges. In some embodiments, the lookup-table can simply include associations between various magnification settings and reticle designs/secondary reticles. In such embodiments, the connection between engagement range and magnification settings can be determined prior to use, with the resulting associations between various reticles and device magnification settings programmed into the lookup-table stored in memory. For example, in certain embodiments, the device could determine an expected engagement range that includes close-range targets, such as targets within 50 yards, based on a magnification setting of 3× or lower. As such, in various embodiments where the secondary reticle is associated with engagement ranges within 50 yards the device can determine that the secondary reticle should be presented to the user. Similarly, where the device determines an expected engagement range that does not include clos-range targets the device can determine that the secondary reticle should not be presented to the user.

If, at decision block 1012, the secondary reticle is configured for target engagement within the expected engagement range then the method 1000 proceeds to operation 1016 where the method 1000 includes displaying the secondary reticle in the reticle display field.

If, at decision block 1012, the secondary reticle is not configured for target engagement within the expected engagement range then the method 1000 proceeds to operation 1020 where the method 1000 includes not displaying the secondary reticle in the reticle display field.
